The stronger the correlation, the closer the points are to a straight line.
Angel bought a piece of artwork that had a value of V dollars.
Over a period of five years the artwork increased in value by 40%.
Which expression represents the current value of the artwork?
A 1.4V
B 0.4v
C v+1.6v
D 1+0.4v
Using proportions, it is found that the expression that represents the current value of the artwork is given by:
A 1.4V
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the initial value was of V, which increased by 40%. Thus, the current value of V is 100% + 40% = 140% of the original, which is equivalent to a proportion of 1.4, that is: 1.4V.
Hence, option A represents the current value of the artwork.

Answer:
y=9 and x=15
Step-by-step explanation:
ok looking at what they give us in the question we can see that we have two equations. to solve for it be will need to combine them together
note that because they use the word sum we know it's addition
y= x-6
x+y=24
now that we have these we can substitute y=x-6 for the y in our addition equaution such that we have it in terms of one variable:
x+ (x-6) = 24
2x-6=24
2x=30
x=15
now going back we can find Y
15+ y = 24
y=9

Step-by-step explanation:
3/4 if the actual length of the shorter segment is 120 ft.
what do I need to multiply 3/4 with to get 1/1 ?
3/4 × x = 1
3 × x = 4
x = 4/3
you feel the aha moment ?
so, when I multiply 120 ft by 4/3 I reverse the "distraction" of showing me only 3/4 of the real thing, and I get the full length of the shorter segment.
120 × 4/3 = 40 × 4 = 160 ft.
and now we know the longer segment is 12 ft longer.
so, it is
160 + 12 = 172 ft long.
so, the equation we just solved was
y = 4/3 × x + 12
with y being the length of long piece, x being the distorted (by factor 3/4) length of the short piece. and 12 is the overall difference between them.

Step-by-step explanation:
Shadow problems almost always involve similar triangles, meaning that shadow lengths and object heights generally have the same ratio. We can use this fact to write proportions related to the measures in this problem.
(i)The ratio of shadow-tip distance to the object height is the same for both objects. For distances in meters, we have ...
x/7 = (x-y)/2
2x = 7(x -y) . . . . . multiply by 14
7y = 5x . . . . . . . add 7y-2x
y = 5/7x . . . . . divide by the coefficient of y
__
(ii)Solving the equation from the first part for x, we have ...
x = 7/5y . . . . . multiply by 7/5
The derivative with respect to time is then ...
x' = 7/5y'
The rate of change of y is given as 5/3 m/s, so the rate of change of x will be ...
x' = (7/5)(5/3 m/s) = 7/3 m/s

-4 × ( +1 - -5 ) × ( +1 - -5 ) ÷ 6 - ( +42 - -5 ) =
Answer:
-71
Step-by-step explanation:
- 4 x (+1 --5) x (+1 - -5) /6 - (42 - -5)
1 - -5 = 6 and 42 - -5 = 47
-4 x 6 = -24
-24 x 6 = -144
-144 / 6 = -24
-24 - 47 = -71
In a recursive function, what is used to determine whether to stop or to continue with another recursive step
Recursive functions are functions whose execution is called from within itself
A condition is used to stop or continue another recursive step
When does a recursive function stop?
As implied earlier, the execution of a recursive function is from within the function itself.
This means that the recursive function will continue its execution, until a condition is met.
This condition is used to determine the execution or the termination of the recursive process
Hence, a condition is used to stop or continue another recursive step

Are 7/-8 and -7/8 equal?
Yes, they are
Because with fractions, you can divide. The rules for multiplying or dividing with negative numbers are that negative * or / negative = positive and that one negative * or / a positive = negative. These fractions here have one negative and one positive, making it so that when you divide, it will be negative.
Hello.
[tex]\mathrm{\displaystyle\frac{7}{-8} \:and\:\frac{-7}{8} \:are\:equal\:}[/tex]
If we divide a positive number by a negative number, we get a negative number.
Let's try.
We can turn both of these fractions into decimals and see if they are equivalent.
The simplest way to turn a fraction into a decimal is divide the numerator by the denominator.
[tex]\mathrm{\displaystyle\frac{7}{-8} = -0.875}[/tex]
Now, let's convert the second fraction into a decimal:
[tex]\mathrm{\displaystyle\frac{-7}{8} =-0.875}[/tex]
[tex]\mathrm{-0.875=-0.875}[/tex]
Therefore, the two fractions are equivalent (equal).
I hope it helps.

Solve each system using substitution.
y = 2x
6x - y = 8
3x + 5y = 2
x + 4y = -4
Answer for 50 BRAINLIST!!!
Answer:
[tex](2, 4)\rightarrow\text{First system}[/tex]
[tex](4, -2)\rightarrow\text{Second system}[/tex]
Step-by-step explanation:
First system:
We can substitute 2x for y:
[tex]6x-y=8\\6x-2x=8\\4x=8[/tex]
Divide both sides by 4
[tex]x=2[/tex]
Substitute 2 for x to solve for y:
[tex]y=2x=2(2)=4[/tex]
[tex](x, y)=(2, 4)[/tex]
Second system:
We can isolate x in the second equation by subtracting 4y from both sides:
[tex]x=-4-4y[/tex]
Now, substitute this value for x in the first equation:
[tex]3(-4-4y)+5y=2\\[/tex]
Distribute the 3 to each term in the parentheses:
[tex]3(-4)+3(-4y)+5y=2\\-12-12y+5y=2\\-12-7y=2[/tex]
Add 12 to both sides:
[tex]-7y=14[/tex]
Divide both sides by -7
[tex]y=-2[/tex]
Now, substitute -2 for y to solve for x:
[tex]x=-4-4y=-4-4(-2)=-4+8=4[/tex]
[tex](x, y)=(4, -2)[/tex]
